Securities registered pursuant to Section 12(b) of the Act:

Indicate by check mark whether the registrant is an emerging growth company as defined in Rule 405 of the Securities Act of 1933 (§230.405 of this chapter) or Rule 12b-2 of the Securities Exchange Act of 1934 (§240.12b-2 of this chapter).

If an emerging growth company, indicate by check mark if the registrant has elected not to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act. ☐

As previously disclosed, on November 16, 2025, Sealed Air Corporation, a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Sword Purchaser, LLC, a Delaware limited liability company (“Parent”) that is affiliated with Clayton, Dubilier & Rice, LLC (“CD&R”), and Sword Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which, subject to the satisfaction or waiver of the conditions set forth therein, Merger Sub will be merged with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent.

In connection with the transactions contemplated by the Merger Agreement, certain employees of the Company (including certain of its current named executive officers, principal financial officer and other executive officers) may become entitled to payments and benefits that may be treated as “excess parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”). To mitigate the potential impact of Sections 280G and 4999 of the Code on the Company and certain executive officers, on December 18, 2025, the Company’s Board of Directors (the “Board”) and its People & Compensation Committee (the “Committee”) approved the acceleration of certain equity awards and cash-based awards with respect to Dustin J. Semach, President and Chief Executive Officer; Kristen Actis-Grande, Chief Financial Officer (and our principal financial officer); Byron J. Racki, President, Protective; and Veronika Johnson, Chief Accounting Officer and Controller, that would have otherwise been payable to Messrs. Semach and Racki and Mses. Actis-Grande and Johnson, subject to execution by each of the executive officers of a Repayment Agreement, as further described below. These actions are intended to benefit the Company by preserving compensation-related corporate income tax deductions for the Company that otherwise might be disallowed through the operation of Section 280G and to mitigate or eliminate the amount of excise tax that may be payable by an executive officer pursuant to Section 4999 of the Code in connection with Section 280G in certain circumstances.

The approved accelerated vesting and payments took one or more of the following forms for each executive officer: (a) payment of the annual bonus that otherwise would be payable in 2026 in respect of fiscal year 2025 (“FY25 Annual Bonus”) with performance for this purpose deemed to be 90% of target (“Accelerated Bonus”), to be paid on or prior to December 31, 2025, and (b) vesting and settlement in shares of Company common stock of certain Company restricted stock units (“RSUs”) held by the executive officer that otherwise would have vested and been settled in 2026 (“Accelerated RSUs”), effective as of December 22, 2025. The Accelerated Bonus and Accelerated RSUs (collectively, the “Accelerated Amounts”), as applicable, offset the corresponding payments or amounts the executive officers otherwise would have been entitled to receive in 2026, thereby precluding duplication of payments. All Accelerated Amounts will be reduced by applicable tax withholdings and are subject to the terms of the Repayment Agreement.

Specifically, the Committee and the Board approved the following accelerated vesting and payments:

In connection with the accelerated vesting and payments described above, each such executive officer will execute a Repayment Agreement providing that the accelerated payments are subject to certain repayment and true-up conditions, as described below.

Specifically, if an executive officer’s employment with the Company is terminated for “cause” or voluntarily by the executive officer other than for “good reason,” (as such terms are defined in the Company’s Executive Severance Plan), prior to the date the FY25 Annual Bonus is paid to the Company’s employees generally in 2026, then the executive officer would be required to repay to the Company the net after-tax amount of such FY25 Annual Bonus within 30 business days following such termination of employment. Moreover, if the FY25 Annual Bonus based on actual achievement of performance goals exceeds the amount of the Accelerated Bonus, the Company will pay such excess amount (less applicable taxes and withholdings) to the executive officer at the same time the FY25 Annual Bonus is paid to the Company’s employees generally. However, if the FY25 Annual Bonus based on actual achievement of performance goals is less than the amount of the Accelerated Bonus, the executive officer will repay to the Company the excess (if any) of the after-tax portion of the Accelerated Bonus over the actual FY25 Annual Bonus (such actual FY25 Annual Bonus amount calculated on an after-tax basis).

Further, if an executive officer’s employment with the Company is terminated (i) for any reason other than death or disability prior to the consummation of the Merger and prior to the date on which the applicable portion of the Accelerated RSUs would have vested in accordance with their original terms or (ii) for “cause” or voluntarily by the executive officer other than for “good reason” (as such terms are defined in the Company’s 2014 Omnibus Incentive Plan) following the consummation of the Merger but prior to the date on which the applicable portion of the Accelerated RSUs would have vested in accordance with their original terms, then the executive officer would (x) to the extent the executive officer still holds any shares of the Company’s common stock received on settlement of the Accelerated RSUs (the “RSU Shares”), immediately forfeit the net after-tax RSU Shares and (y) to the extent the executive officer has sold or transferred any RSU Shares, promptly repay to the Company an amount equal to the fair market value of such RSU Shares as of the date of such sale or transfer within 30 business days following such termination of employment.

The description of the Repayment Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Form of Repayment Agreement, a copy of which is filed as Exhibit 10.1 herewith and is incorporated by reference herein.

Re: Repayment Agreement

Dear [ • ]:

In connection with the transactions contemplated by that certain Agreement and Plan of Merger by and among Sword Purchaser, LLC, Sword Merger Sub, Inc. and Sealed Air Corporation (the “Company”), dated as of November 16, 2025 (the “Merger Agreement”), you may become entitled to payments and benefits that may be treated as “excess parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (the “Code”). Pursuant to the Merger Agreement and associated Company Disclosure Letter, the Company is permitted to take certain steps to mitigate the potential impact of Sections 280G and 4999 of the Code (the “280G Mitigation”).

In connection with the 280G Mitigation, the Company has determined to (i) advance the payment of your 2025 Annual Incentive Program (“AIP”) bonus in the amount of $[ • ] (less applicable taxes and withholdings) based on an estimate of performance achievement of 90% of target, to be paid on December [ • ], 2025 (the “2025 AIP Advance Bonus”), and (ii) accelerate the vesting of [ • ] shares subject to your time-based Restricted Stock Unit award which were scheduled to vest during the 2026 calendar year under the Company’s 2014 Omnibus Incentive Plan (the “Plan”), with such acceleration effective as of December [ • ], 2025 (the “Accelerated RSUs”).

You and the Company hereby acknowledge and agree to the following:

1. AIP Bonus:

a. If the amount of your 2025 AIP bonus based on actual achievement of the performance goals (as determined by the Company’s Compensation Committee) (the “Actual AIP Bonus”) exceeds the amount of the 2025 AIP Advance Bonus, the Company will pay such excess amount (less applicable taxes and withholdings) to you at the same time 2025 AIP bonuses are paid to the Company’s employees generally. If the Actual AIP Bonus is less than the 2025 AIP Advance Bonus, you will repay to the Company the excess (if any) of the after-tax portion of the 2025 AIP Advance Bonus over the Actual AIP Bonus (with the Actual AIP Bonus calculated on an after-tax basis assuming the Actual AIP Bonus had actually been paid to you at the same time that the 2025 AIP bonuses are ordinarily paid) within 30 business days following the date that the Company makes such determination and notifies you of the applicable repayment amount.

b. In addition, you hereby agree that you will promptly repay the net after-tax amount of such 2025 AIP Advance Bonus in the event you resign from employment without “Good Reason” or are terminated for “Cause” (each as defined in the Company’s Executive Severance Plan) prior to the date AIP bonuses are paid to employees generally in 2026, with such repayment to occur within 30 business days following such termination.

2. Accelerated RSUs.

a. In the event (i) of your Separation from Service (as defined in the Plan) for any reason other than due to your death or Disability (as defined in the Plan) prior to the consummation of the transactions contemplated by the Merger Agreement (the “Closing”) and prior to the date on which the applicable portion of the Accelerated RSUs otherwise would have vested or (ii) you resign from employment without “Good Reason” or are terminated for “Cause” (each as defined in the applicable award agreement pursuant to which the Accelerated RSUs were granted) following the Closing but prior to the date on which the applicable portion of the Accelerated RSUs otherwise would have vested in accordance with their terms, then you agree that (x) you shall immediately forfeit any net after-tax shares of Stock (as defined in the Plan) received on settlement of the Accelerated RSUs (the “RSU Shares”) to the extent you still hold such RSU Shares and, to the extent you have transferred, sold or otherwise disposed of any such RSU Shares (including, for the avoidance of doubt, in connection with the Closing), you shall promptly repay to the Company an amount equal to the Fair Market Value (as defined in the Plan) of such RSU Shares as of the date of such transfer, sale or disposition, with such repayment to occur within 30 business days following such termination. For the avoidance of doubt, if you resign from employment for “Good Reason” or are terminated without “Cause” following the Closing or if your termination occurs due to your death or Disability, you shall not be obligated to repay or forfeit any RSU Shares or the Fair Market Value of such RSU Shares as of the date of any such transfer, sale or disposition.

In the event of any default by you in the repayment obligations described above, to the extent permitted by applicable law, in addition to any other remedy which may be available at law or in equity, the Company reserves the right to reduce any payments due to you from the Company or any subsidiary following the termination of your employment to satisfy any such repayment obligations.

This letter may be delivered electronically and may be executed in counterparts, each of which shall be deemed an original but all of which together shall constitute one and the same document. This letter shall be governed by and construed and enforced in accordance with North Carolina law without regard to the conflict of laws provisions thereof. This letter constitutes the entire agreement between you and the Company with regard to the subject matter hereof and supersedes any and all prior agreements, whether written or oral, between the parties with respect to the subject matter herein. This letter may be amended or modified only with the written consent of you and the Company.
